Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disease characterized by mineralocorticoid resistance with subsequent salt wasting, hyperkalemia, metabolic acidosis, and elevated plasma renin and aldosterone levels.Patients and methods: We report a male newborn that presented with failure to thrive and sustained hyponatremia during his early postnatal period. He was conceived after IVF (twin pregnancy) and prematurely born by cesare...

The pandemic has changed habits in families around the world. Eating habits and physical activity were directly impacted by social distance. The first year of the pandemic left its mark on children’s health. The purpose of this analysis was to evaluate the relationship between the first year of the pandemic and the serum lipid profile in children who underwent lab tests in a private laboratory in Curitiba-PR.Methods: Observational a...

Background: Most congenital adrenal hyperplasia (CAH) patients carry mutations derived from conversion events involving the pseudogene, and the remaining carry new mutations varying according to ethnicity. A good genotype-phenotype correlation is observed, allowing the use of molecular analysis in clinical practice.Objective and hypotheses: To review the molecular diagnosis in a large cohort of CAH patients in order to create a diagnostic panel in our po...

Background: The ‘External Masculinization Score’ (EMS) is an objective method of scoring undervirilized genitalia in infants but may require further adaptation to capture the appearance of the genitalia more comprehensively across the phenotypic spectrum.Objective: To develop and validate a non-binary, standardized score that describes the range of appearance of external genitalia.Method: The external genitalia score (EGS...

Background: The diagnosis of 46,XY disorder of sex development (DSD) due to 5-alpha reductase 2 (5α-RD2) deficiency has been based on testosterone:dihydrotestosterone (T:DHT) ratio, urinary steroid profiling and mutational analysis of SRD5A2 gene. The biochemical hallmarks of 5α-RD2 deficiency include increased T:DHT ratio. However, several difficulties are observed in the DHT measurement leading to misdiagnosis. The mutational analysis of the SRD5A2 has been propose...

Introduction: Gonadotoxicity associated with chemotherapy of hematologic malignancies has been described mainly in adults, focused on the sensitivity of germ cells. Little attention has been placed on Sertoli cells during childhood and puberty, even though Sertoli cell development is essential for adult spermatogenesis.Objective: To assess function of the pituitary-testicular axis, with emphasis on Sertoli cell function,...

Background: The aetiology of congenital hypopituitarism (CH) is unknown in the majority of patients. In our cohort of 200 cases, it was possible to establish the genetic cause in only 13 patients (6.5%). Copy number variants (CNVs) have been implicated as the cause of genetic syndromes with previously unknown aetiology.Objective: To study the presence of CNVs and its relevance in patients with CH of unknown cause associated with complex phenotypes.<p...

Objectives: The etiopathogenetic of childhood obesity is related to genetic and environmental factors: not only caloric intake or physical activity have an important influence, but also circadian rhythms, including healthy sleep.The objectives of this study were: a) to analyze the different patterns and duration of sleep, eating habits, meal schedules, time dedicated to exercise and screens of obesity children; b) to evaluate its possibl...

Objective: KIMS (Pfizer International Metabolic Survey) was a postmarketing surveillance study of growth hormone (GH) replacement in adults and adolescents with GH deficiency (GHD) that concluded in October 2012. This analysis aimed to evaluate the overall safety outcomes from the full cohort of GH-treated patients of KIMS.Methods: Data were collected on adults and adolescents with confirmed GHD and closed epiphyses trea...

Background: Steroid 21-hydroxylase deficiency (21OHD) is the most common form of congenital adrenal hyperplasia. Patients present with cortisol and aldosterone deficiency as well as with hyperandrogenism, leading to virilisation in females and early adrenarche in both sexes. Requiring life-long glucocorticoid (GC) replacement, patients frequently experience daily fluctuations between GC overexposure and deficiency. Increased prevalence of metabolic disease con...
